The Rooftop Singers were an American progressive folk-singing trio in the early 1960s, best known for the hit "Walk Right In". The group was composed of Erik Darling and Bill Svanoe (vocals, guitar) with former jazz singer Lynne Taylor (vocals).
Darling put the group together in June 1962 specifically to record an updated and uptempo version of a 1929 Gus Cannon folk blues song, "Walk Right In". The trio recorded the song for Vanguard Records, with updated lyrics and an arrangement featuring paired 12-string acoustic guitars. The record became the most successful single in Vanguard's history.
